Connecting the machine to the mains
The electrical installation is adopted to the supply Line TN-S (L1, L2, L3, PE). In case of four-lead
supply line the connecting should be carried out respecting all valid regulations. The electrical
equipment has no main protection. Such a protection should be made on the supply line using
installation disconnectors of category C-35A. The machine tool should be fed with a cable OPd 5
x 6 mm
2
.
Before connecting the machine tool to the mains one has to check the technical condition. If the
resistance is lower than 0.5 M
Ω
m one has to dry all the equipment.
You must not connect the machine tool to the mains without having measured, previously, the
insulation condition of the equipment. A protection network system should be provided according
to the regulations in force.
The whole wiring system as well as the motors will function correctly if the supply voltage is not
below 95 percent or higher than 110 percent of its nominal value.
The entry of the feeding cable is shown in the drawing presenting the foundation.
The length of cable ending allowance for connection should be about 1 m. The leads of feeding
cable should be connected to appropriate terminals.
3.4
Connecting the machine to the exhaust installation
Before connecting the machine to the plant exhaust system one should check if the system satis-
fies the conditions started in Section1..
After having inspected the system one should connect the machine tool to connector pipes using
a flexible hose
?
120.
Place the hose on the connector pipe and fix it with a pressure band.
Notice !
1.It is forbidden to connect the machine to the shaving exhaust system to which electrical, weld-
ing or other devices that can generate sparks have already been connected.
2.It is forbidden to work on the machine tool without having connected the exhaust system- you
risk losing the warranty when not observing that regulation.
